Linear verrucous hemangioma.

Verrucous hemangioma is a rare, vascular malformation. It is usually present at birth, but there is often a gradual increase in size and number with age; occasionally it presents in later adulthood. The lesions usually present as hyperkeratotic, bluish, and partly confluent papules and plaques. Linear verrucous hemangioma is an even more rare presentation described in very few published reports. We report a 30-year-old male patient with linear verrucous hemangioma who experienced a sudden increase in the size of his verrucous hemangioma during adulthood.
